HOSE-CLAMP.

SPECIFICATION forming part of Letters Patent No. 747,811, dated December 22, 1903.

Application filed August 10, 1903- Seri l No. 169,045. (No model.)

To all whom it may concern;

Be it known that I, WARD O. WALKER, a citizen of the United States, residing at the city of Battlecreek, in the county of Calhoun and State of Michigan, have invented certain new and usefullmprovements in Hose- Olamps, of which thefollowing isa specifica tion.

This invention relates to improvements in hose-clamps.

The objects of the invention are, first, to provide an improved hose-clamp which may be readily'applied without the use of special tools; second, to provide an improved hoseclamp formed of a single piece of sheet metal which may be quickly applied and securely adjusted or released; third, to provide an improvedhose-clamp which is economical to produce and strong and durable and convenient to use.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearlydefined,and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a partof this specification, in which- Figure 1 is a side elevation View of my improved hose-clamp shown in position on a section of hose. Fig. 2 is a detail cross-sectional view taken on a line corresponding to line 2 2 of Fig. 1. Fig. 3 is an enlarged detail plan view of my improved hose-clamp distended. Fig. tis a detail longitudinal.

sectional view taken on line 4 4 of Fig. 3. Fig. 5 is an enlarged detail cross-sectional view taken on line5 5 of Fig. 3. Fig. 6 is an enlarged plan view of the blank of which my improved hose-clamp is made before the same is formed up.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and

similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A represents a section of hose.

Myimproved hose-clamp consists of a band portion B, which is adjusted to encircle the hose, and ahead por'tion adapted to retain the The band B is provided and is retained in position by the rearwardly- [projecting pawl a, which is adapted to engage the perforations b therein. The forwardly-projecting loop 0 is provided for use in drawing the band about the hose. This is accomplished by inserting a suitable lever through the loop into one of the perforations b in the band and operating the lever, the loop serving 'as a fulcrum. The band may thus be drawn tight about the hose. The band is retained in its adjusted position by the rearwardly-projecting pawl 01/, which is adapted to engage the perforations in the band as they are passed under it.

The band B is arranged over the forwardlyprojecting tongue I) on the head B. This tongue 17 when the band is drawn tight upon the hose completes the contact with the hose at the point where the band passes through the head. (See Figs. 2, 3, and 4.)

As illustrated, my improved hose-clamp, is formed of a single piece of sheet metal, the blank therefor being illustrated in Fig. 6. The head B is slitted at 00 and 'J to form the tongue I) and the pawl a. The portion a is folded up at right angles to the body and the pawl a" rearwardly and downwardly. (See Figs. 3, 4, and 5.) The band is inserted through the opening made by the tongue b and under the pawl 01.. are turned up to form the loop 0. (See Figs. 3 and 4.) The lugsaare turned inwardly to form rests or supports for the pawl a, so that the same is held securely in place. To the rear of the pawl a is cut a-V-shaped hole'b to remove a portion of the stock, so that it may be more readily conformed to the hose.

From the foregoing description it is evident that my improved hose-clamp is very simple in its constructiomand economical to produce. and drawn tightly upon the hose without the use of special tools, a nail or the like being found entirely satisfactory.

If it is desired to release the clamp, the

The side portions 0 N The same maybe secured in place pawl a can be readily disengaged from the perforations and the band Withdrawn from the head.

The structure is also very light in weight, although it is strong and durable.

As constructed for use the structure is very compact and forms but a slight projection on the hose to which it is applied.

In the accompanying drawings the head portion, and particularly the pawl a, are enlarged to show their structure and project considerably more than in structures made for actual use.

My improved hose-clamp is equally desirable for use on hose of very large and small diameter.

I have illustrated and described my improved hose-clamp in the form preferred by me on account of its economy in construction and convenience in use. I am aware, however, that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hose-clamp formed of a single piece of sheet metal consisting of a band portion B having perforations 11 therein; a head portion B adapted to receive said band; a forwardly-projecting tongue I); a rearwardlyprojecting pawl ct" adapted to engage said perforations b; inturned lugs a for sustaining said pawl a; and a forwardly-projecting loop C.

2. A hose-clamp formed of a single piece of sheet metal consisting of a band portion 13 having perforations b therein; a head portion 13 adapted to receive said band; a rearwardly-projecting pawl a adapted to engage said perforations b; inturned lugs a for sustaining said pawl a; and a forwardly-projecting loop 0.

3. A hose-clamp formed of a single piece of sheet metal consisting of a band portion B having perforations b therein; a head portion B adapted to receive said band; a forwardly-projecting tongue I); a rearwardlyprojecting pawl ct adapted to engage said perforationsb; and a forwardly-projecting loop 0.

4. A hose-clamp formed of a single piece of sheet metal consisting of a hand portion B having perforations b therein; ahead portion adapted to receive said band; a rearwardly-projecting pawl 0, adapted to engage said perforations I); and a forwardly-projecting loop O.

5. A hose-clamp formed of a single piece of sheet metal consisting of a band portion; a head portion B adapted to receive said band; a rearwnrdly-projecting pawl ct" adapted to engage said band; and a forwardly-projecting loop 0.

6. In a hose-clamp, the combination of a band; a head adapted to receive said hand; a rearwardly-projecting pawl on said head adapted to engage said band; and a forwardly-projecting loop on said head, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
